Numerical Modeling of Pore Fluid Flow in Reconstructed Porous Media

In this paper, the numerical simulation of pore fluid flow in reconstructed porous media was carried out. The 3D porous computational domain was reconstructed based on the 2D images from micro CT scanner equipment. The Shan-Chen type lattice Boltzmann method (LBM) was adopted to establish the numerical model to predict the two-phase flow in the complex porous domain. The pore space is in micro/mini scale and the surface structure will have an influence on the pore fluid flow. Different surface tension coefficients were adopted in the numerical simulation to analyze its effect on the two-phase flow in complex porous media.
